I am unsure HOW I did it, but I as trying to take a screen shot with CMD-SHIFT-4....
I somehow ended up with something different than normal. The top edge, and left edge of the safari window ended up with some odd looking "rulers," each was marked with lines, and moving the mouse would select what seemed to be predefined segments of the window.
Along with the rulers and predefined marks on the ruler, it would show guidelines along each segment as you moved the mouse to each "predefined segment".
I clicked on one, and it took a screen shot of that segment.
I have been unable to replicate it. I wish I had taken a photo of it.
